We’re looking for a Middle+ PHP Developer (Laravel) who enjoys moving fast, taking real ownership, and shipping production-ready solutions with high engineering standards.

Location: Stockholm, Sweden (office/remote). Permanent location in the EU or Ukraine is required (we can only consider candidates legally based in the EU or Ukraine).

Join Söderberg & Partners Heartpace AB, a Swedish product company building innovative, reliable software for the European market. We’re looking for a Backend Developer (Laravel) with around 3 years of experience who enjoys solving real production problems, supporting users and internal teams, and improving system stability.

This role sits close to production: you’ll handle incoming technical issues, investigate bugs and incidents, make safe fixes, and help us prevent repeat problems through better monitoring, automation, and documentation.

What we offer

• Flexibility: work fully remote.
• Career growth: clear development paths, mentorship, and coaching from senior engineers.
• Modern tech stack: Laravel, AWS (S3, ECS, RDS), Docker, event-driven architecture, and more.
• Professional development: we cover certifications, conferences, and access to Udemy courses to support your growth.
• AI-first enablement: we actively automate workflows with AI — and we’ll compensate relevant AI subscriptions you need for your work.
• Work-life balance: no overtime culture and generous vacation policies.
• Security matters: we are ISO 27001:2022 certified, meaning we take information security and operational discipline seriously.

What you’ll do

• Provide technical support for our product: investigate and resolve production issues, bugs, and user-reported problems.
• Triage incoming requests: clarify symptoms, reproduce issues, identify root cause, and communicate progress/status clearly.
• Fix backend issues in Laravel: implement safe, well-tested changes and deploy via our standard release flow.
• Work with databases (primarily SQL): analyze data issues, write/debug queries, and help prevent data integrity problems.
• Use logs, metrics, and tracing to debug effectively; improve observability (better logs, alerts, dashboards).
• Collaborate with Product, QA, and DevOps to ensure smooth delivery and reliable operations.
• Contribute to continuous improvement by:
  • writing/supporting runbooks and internal documentation
  • automating repetitive support tasks
  • suggesting and implementing small refactors to reduce incidents
• Use AI tools to speed up debugging, writing documentation, creating test cases, and summarizing incidents—while keeping quality and security intact.

We value

• High performance / results-first: solving the real problem and preventing it from coming back.
• Ownership: take responsibility for issues from report → diagnosis → fix → follow-up.
• Systems thinking: understand how changes affect reliability and users.
• Fast execution with integrity: speed and safe changes.
• Continuous improvement: learn, document, automate, and level up our support maturity.

You’ll thrive here if you…

• Enjoy debugging and turning messy issues into clear fixes.
• Communicate well under uncertainty (and ask good questions early).
• Like working close to real users and real production constraints.
• Prefer practical improvements over process theater.

What we’re looking for

• Around 3+ years of software development experience with Laravel, Yii.
• Solid fundamentals: OOP, clean code practices, and version control with Git.
• Basic experience with AWS and cloud environments (e.g., S3/ECS/RDS — not necessarily deep expertise).
• Working knowledge of PostgreSQL and MongoDB: writing queries, debugging data issues, understanding indexes at a basic level.
• Comfortable with Docker-based local development and working with CI/CD pipelines (at least as a user).
• Strong problem-solving skills, attention to detail, and a service mindset toward internal/external users.
• English: Upper-Intermediate+ for collaboration and documentation.
• Language bonus:
  • Swedish is a plus.
  • Ukrainian/Russian is a plus for smoother communication with part of the team.
• AI usage experience: practical experience using AI tools to support development/support workflows (we’ll support and compensate relevant subscriptions).

Interview process (3 steps)

1. Screening interview with the Recruiter.
2. Technical interview with the Tech Lead + practical debugging/support task.
3. Final approval interview with the CTO.

Why join us?

At Söderberg & Partners Heartpace AB, you’ll work on a product that matters — in a role that builds strong engineering fundamentals through real-world debugging, production support, and reliability improvements.
